Definitions 1. Prism: A solid with bases that are parallel and sides that are parallelograms. 2. Base: The surface that a 3D figure stands on. 3. Face: A side of a 3D figure. 4. Lateral Face: A face of a solid that is not a base. 5. Edge: A place where 2 faces meet. 6. Surface Area: The area of a 3D figure's net. 7. Right Prism: A prism where the lateral faces meet the bases at right angles. 8. Oblique Prism: A prism where the lateral faces do not meet the bases at right angles. 9. Lateral Area: The surface area of a 3D figure, without the bases. 10. Pyramid: A polyhedron with a base and triangular faces that make a point above the base. 11: Regular Pyramid: A pyramid whose base is a regular polygon and whose faces are all congruent. 12. Vertex of a Pyramid: The point at which the lateral faces all meet. 13. Altitude of a Pyramid: How far above the base the vertex is. 14. Net: A 2D figure which can be folded along its edges to make a 3D figure.

Formulas 1. Pyramid: Lateral Area = 1/2ps Total Area = 1/2ps + b Volume = 1/3bh 2. Cylinder: Lateral Area = 2(pi)rh Total Area = 2(pi)rh + (pi)r^2 Volume = (pi)r^2*h 3. Cone: Lateral Area = (pi)rs Total Area = (pi)rs + (pi)r^2 Volume = 1/3(pi)r^2*h 4. Sphere Surface Area = 4(pi)r^2 Volume = 4/3(pi)r^3
